A 17-year-old boy became the youngest person to sail solo around the world with assistance when he returned to UK waters following his nine-month voyage.

Mike Perham, from Potters Bar, crossed the finishing line between Lizard Point and Ushant, France, in the 50ft racing yacht Totallymoney.com at approximately 9.55am, his team said. He set off last November and has battled with 50ft waves, gale force winds and numerous technical difficulties during the 30,000-mile challenge.

His father Peter Perham said: "I am delighted and I know Mike is very, very excited." Mike originally set off aiming to complete the challenge non-stop but technical problems forced several stops, meaning his world record is the youngest solo circumnavigation with assistance.
